I have to design storage building with 4 floors, 100x100´ (lxw), 85´height with using of prefabricated concrete elements.
The posts and girders are in 20´x20´grid, ceilings could be from prestressed hollow panels (thickness 12´´) with
concrete slab (membrane) (th. 3,5´´) on the top of the...
Does anybody know if is it necessary to use secondary protection of concrete for piles in underground water which contens 83 mg/l CO2 aggressive(0,0083% per weight unit)or if is it possible to take only resistant basic material (concrete)? Water is acid (6,1 pH) and very hard.
Thanks.

Does anyone know something about dynamic module Es,dyn used for design of footing of wind energy plant? I´d like to know what is relation between Es, stat and Es,dyn.
Thanks.
Anyone have any information about dynamic modulus Es,dyn used for design of footing of wind energy plant? I´d like to know what is relation between Es, stat and Es,dyn.
